Seeing two of those beasts going down, Rogan smiles slightly. "You picked the wrong targets!"
Rogan moves to follow the last Bothrii and swings his torch. It seems teribly unwieldy compared to his hammer, but he might still land a hit.
Spoiler: attack(1d20-1)[6] for (1d6+2)[8] or (1d4+2)[5] damage.
+1 point of fire damage
EDIT:
As the torch hit the stone floor instead of the enemy, he lets out an angry shout and prepares to defend himself, should the beast strike back.
